There are a variety of peas you can plant. You can always plant more than one variety to expand your menu options. I am planting sugar snap and Alaska peas. Peas do need a trellis to climb up. They produce more if they have a support to grow up on. A pea trellis does not have to be fancy or expensive. But, it does have to be sturdy. You can make a trellis out of recycled items you have around your house. My pea trellis is actually a leftover pig fence panel. I plant peas on both sides of my trellis.
Peas are easy to plant. I plant them directly outdoors in my garden. There is no need to start them indoors. They do not transplant well. They also prefer cool weather and will grow beautifully until the weather starts to heat up. And when it gets too hot they will quit producing. I soak my peas overnight to help them to germinate easier. We are still in a severe drought in Texas so they need all the help they can get to get off to a good growing start. You just follow the directions on the back of the seed packet. I plant the seeds about 1 inch deep and about 2 inches apart. Cover the seeds with soil and water them. Be careful not to wash the soil away and expose the seed. They will germinate in a week and will be ready to eat in about 2 months.
